Figure 4: System - Fresnel Zone
A wireless link is considered non LOS if natural or man-made structures block the visible
path between the base station and the subscriber. In this case, a wireless link can be
established only if a reflective path can be established between the base station and
subscriber.

2.6.4 Channelization
The base station is a frequency-specific system, with the frequency band defined by the
transceiver unit. The use of the operating band must be in accordance with European
Conference of Postal and Telecommunications Administrations (CEPT)
Recommendation 14-03.
The base station divides the available frequency band into channels. Allocation of
channels during deployment is dependent on spectrum availability in the licensed FWA
band and local licensing requirements and conditions. Channel selection allows planners
to obtain the maximum geographic coverage, while avoiding frequency contention in
adjacent sectors.
